PROCESS FOR FORMING CURVED TUBULAR GASINGS FOR HORSE-COLLARS.

Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed August 20, 1912. Serial No. 716,060.

T all whom it may concern Be it known that I, LEONARD J. POWERS, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Processes for Forming Curved Tubular Casings for Horse- Collars, of which the following is a specification.

My invention relates to improvements in processes for forming curved tubular casings for horse-collars and the like, and the object of my improvement is to supply a method whereby without waste of material, oblong or rectangular strips or pieces of textiles or other similar materials may be manipulated and caused to assume a curved tubular form to produce such casings. This object I have accomplished by the methods which are hereinafter described and claimed, and which are explained and illustrated by means of the aid of the drawings hereto annexed, in which:

Figure 1 is a plan of a simple rectangular strip of flexible fabric not yet operated upon. Fig. 2 is a plan of a similar strip in which the first stage of the process is shown, while Figs. 3 and 4: show two subsequent and successive stages of the process, and Fig. 5 shows a tubular casing as formed by the final stage of the process. Fig. 6 is a perspective view of a horse-collar which comprises roll whose casing is formed by the said improved process.

Similar numerals of reference denote corresponding parts throughout the several views.

Heretofore, in order to form a curved hollow tube or casing of flexible materials or textiles, such as are used and stuffed to be comprised in horse-collars, it has been the custom to use pieces of material of which one or more ends or parts are cut of a curved contour to thereby bring out a curve in the form of the casing when completed. This method of cutting the material was wasteful, since parts of the material between successive cuttings were useless and discarded. In my improved process of cutting the ma terial and forming the cut-out parts into such casings, I cut the material simply into rectangular strips 1 of the desired width and length as bases for the casings, which obviously results in saving all the material, especially when the pieces 1 are cut off a bolt having a width of the same dimension as the length of the piece.

In order to produce a desired curvature in the tubular casing when completed, I follow the following described steps or stages in the process, as indicated by the drawings in Figs. 2 to 5 inclusive. In the first stage, one or more parts of one of the longitudinal edges of the strip 1 is gathered at 2 and 3 and the gathered parts sewn to draw them permanently together, which produces curves in that edge of the strip. In the next stage, I form on the opposite longitudinal edge of the strip, opposite to said gathered places 2 and 3, triangular folds or plaits, and said plaits are then sewn together to produce inwardly projecting folds 4L and 5, which causes other curvatures in said edge. The final stage is the uniting by stitching or otherwise of the said longitudinal edges of the strip at 6, and the hollow tubular casing thus formed is as shown in Fig. 5, where permanent curves in the tube are caused by the above described proc esses. As shown in Fig. 6, in a finished horse-collar, such a casing is stuffed, its ends closed, and it is secured upon the collar 7 as shown at 1 in a desired position and relation, and preserves its shape as made until worn out.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

The process of forming tubular roll-casings for horse-collars, which comprises gathering and securing spaced parts on one long side edge portion of an oblong piece of flexible material to contract such parts, then forming and securing on the other long side edge-portion opposite said spaced parts triangular plaits, and securing the long side edges together to produce a longitudinally curved roll-casing.

Signed at Waterloo, Iowa, this 31st day of July, 1912.

LEONARD J. POWERS.
